Building site from WP import fails with 'Task generation 'render_site' has duplicated definition...' #2315

Closed SpotlightKid closed 8 years ago

SpotlightKid commented 8 years ago

(As first reported in #2246)

I exported my Wordpress blog and imported it with "nikolo import_wordpress .xml". When I try to build the site in the newly created dir new_site (i.e. with conf.py file created by the import process), I get the following error:

$ nikola build
Scanning posts........done!
ERROR: Task generation 'render_site' has duplicated definition of 'render_tags:output/categories/midi.xml'

Two of my blog posts use the same tag "MIDI`:

$ grep -ri 'tags:.*midi' posts/*
posts/article/882.meta:.. tags: German,JX-3P,MIDI,Novation,Organix,Remote SL,Roland,Musik,Synths
posts/article/598.meta:.. tags: ELKA,EM 13,Gear,MIDI,Musik,Review,Synth,Midi,Musik,Synths

Only if I remove the "MIDI" tag from both files found by the grep command shown above, nikola build succeeds. It is not enough to remove the tag only from one file, even if I delete output, cache and .doit.db between build attempts.

SpotlightKid commented 8 years ago

Just did another test: if I change the tag name from "MIDI" to "Midi" (i.e. not all uppercase), the site builds fine.

Do you have any categories named MIDI? Is your category prefix changed from the default?

Try restoring uppercase tags and adding a debug print after [https://github.com/getnikola/nikola/blob/master/nikola/plugins/task/tags.py#L374](line 374 in tags.py):

print(tag, output_name, lang, posts, is_category)

Run nikola build -v 2 and show us the output.

Do you have any categories named MIDI?

Yes, there's also a Wordpress category "Musik>Midi" (permalink form "midi").

Is your category prefix changed from the default?

In the Wordpress Settings-Permalinks, category-base is set to "category" and tag base is set to "tag". The nikola config is unchaged from the one created by "import_wordpress".

Run nikola build -v 2 and show us the output.

$ nikola build -v 2

This is something we did not expect users to do. I’ll try to fix it.

SpotlightKid commented 8 years ago

The first form must come from the tags of the article in Wordpress, the second from the category.

Kwpolska commented 8 years ago

There, now it would complain. I thought the WordPress compiler did something different to categories?

SpotlightKid commented 8 years ago

Now I get the following error output (with a fresh import from the Wordpress XML-Export):

IMHO, there's a mismatch between what the import_wordpress command generates and what build expects.

done!
Kwpolska commented 8 years ago

Well, I got the order a bit wrong. Does 5372c8b look sane?

SpotlightKid commented 8 years ago

No, sorry. Now we're back to the original error:

Anyway, IMHO the error is in the export. Why do the tags and categories get all mixed into tags?

$ nikola build -v 2
Scanning posts........done!
ERROR: Task generation 'render_site' has duplicated definition of 'render_tags:output/categories/midi.xml'
felixfontein commented 8 years ago

There, now it would complain. I thought the WordPress compiler did something different to categories?

Only if you specify --export-categories-as-categories.

SpotlightKid commented 8 years ago

Ok, it seems we have three different problems:

  1. nikola build doesn't handle multiple tags differing only in case.
  2. When used without options, import_wordpress generates tag lists, which nikola can't handle 1.). This is at least a documentation deficiency, IMHO.
  3. When using --export-categories-as-categories only the first category is preserved. Maybe there should be an option to include additional categories as tags and output a warning, if this produces tags, which lead to problem 1.).

Why is this issue labelled as "user error" then?

felixfontein commented 8 years ago

Re 3: all categories are stored in categories:, but aren't added to tags. I needed that for my site, as I'm using a slightly different tags+categories plugin for my needs (which is closer to original WordPress).

Re "user error": no idea.

SpotlightKid commented 8 years ago

import_wordpress outputs warnings like:

[2016-04-08T16:45:35Z] WARNING: import_wordpress: Post "posts/264" has more than one category! Will only use the first one.

So the problem is actually not that the import drops categories (it doesn't), that building the site uses only the first category, correct? I think that doesn't really come across clearly from the command's help text and this message.

Kwpolska commented 8 years ago

It should drop categories, because we don’t support multiple categories in core.

Kwpolska commented 8 years ago

I think I got 0af1770 right.

SpotlightKid commented 8 years ago

So the problem is actually not that the import drops categories (it doesn't)

It should drop categories

Sorry, that was misleading. category:: only has the first category, the additional meta keyword categories:: contains all the original categories.

felixfontein commented 8 years ago

Nikola ignores categories:, it only cares about category:. I added the code to store all categories in categories: so that nothing would be lost.

(In Nikola v8, categories will probably vanish completely, see #1718. But as soon as #2107 leads to something useful, it will (hopefully) be possible to re-add categories in a simple way via plugins, and then also possible to easily allow multiple categories per post without big hacks.)
